The ISG motor by three-in one integrated of HEV hydrid car’s front drive is more advanced than the BSG motor. ISG motor with modular design, integrated into several standardized three-in-one units for different car models as needed.
1.Integrate a high-voltage ISG motor with rated power of about 10KW and peak power of about 15KW (low-voltage and high-voltage battery packs), 6-speed dry dual-clutch, and a high-power drive motor (optional with different power motors to form several models). Reducer and differential. The three-in-one system of the dual motor front drive motor is suitable for the DM dual mode hybrid vehicle. Choose three-in-one electric drive with different power drive motors, such as 110KW, 160KW, to achieve different performance. Add rear-drive motor to form an electric four-wheel drive model. Can match turbocharged engines, as well as low-cost, low-noise, naturally aspirated engines
2.Integrated with a high-voltage ISG motor with rated power of 15KW and peak power of about 30KW, 2-speed dry dual-clutch module (for two gear shifts, equivalent to 5 or 6 gears of fuel vehicles), a high-power drive motor and reducer The differential forms another type of dual motor pre-driver three-in-one system. Compared to the dual-mode hybrid, the gearbox structure is simplified, and only two high-speed gear positions are retained, which enhances the power of the ISG motor. The start and low-speed are completely driven by the motor. When the speed is increased, the ISG motor and the battery are powered together. The electric drive three-in-one system can be used as a pre-mixing hybrid, and the rear-drive motor can be used as a four-wheel drive hybrid to match the turbocharged engine, a low-cost, low-noise, naturally aspirated engine. According to the torque supported by the dual clutch module, the motor power can be driven into several models.
3. Integrate a 90V voltage ISG motor with rated power of 15KW and peak power of 30KW, 6-speed dry dual clutch module, a peak power of about 30KW drive motor, reducer differential, and an electric drive suitable for HEV hybrid Combine a system. It can be configured with a small capacity battery of about 3KW, and the weight and cost are lower than PHEV. It can be matched with a turbocharged engine, a low-cost, low-noise, naturally aspirated engine. According to the torque supported by the dual clutch module, it can be divided into two models.
4. On the basis of HEV hybrid, it is not equipped with a drive motor, only BSG motor, which is the lowest cost light mixing system. The motor has large power torque and large belt transmission efficiency. The motor is driven at the start and low speed, which speeds up quickly and has smooth and comfortable driving experience. There is no need to frequently shift gears in the start and middle and low speed stages, and the double clutch does not require long time and half linkage, which completely solves the double clutch problem.
BSG motor is the belt-driven integrated starter generator, it is developed for cost-efficient mass hybridization, such as advanced stop-start, coasting and electric boost save 13% to 20% of fuel.
In a mild-hybrid application the 48 volt electric motor replace the 12 volt alternator and is directly mounted to the engine via a belt.
5. The ISG motor is directly connected to the engine, and the maximum speed matches the engine by about 6000 rpm, which is costly. The advantage is that the drive is more direct, and the power torque of the ISG motor can be made even larger. The BSG motor can be made into a high-speed motor through belt drive, which is low in cost. If the belt drive and BSG motor power torque is sufficient, the belt drive efficiency is high enough and the durability is good enough. The solution using BSG motor has a cost advantage. The corresponding electric drive three-in-one system does not integrate the ISG motor, and other integrated modules remain unchanged. Minimize changes to existing systems.
BSG motor plus electric drive three-in-one unit, or integrated electric drive three-in-one unit of ISG motor (ISG motor replaces BSG motor function), can be combined into three-in-one for light-mix, HEV, PHEV, different performance electric drive Standardized units, assembled to a variety of hybrid cars such as cars, SUVs, MPVs. Power system and chassis are standardized, integrated and modular. Minutes of skinning for different appearances, a variety of styles.
From road testing to market, it only takes one or two month,Introduce new models and sell different types of car at the same time or gradually,according to the sales situation, the models with poor sales are eliminated or redesigned, and the sales star car is retained.
